How do geologists locate the center of an earthquake? check all that apply.

they use seismic waves.
they compare worldwide data.
they collect data from seismographs.
they measure arrival times of surface waves.
they draw squares on maps for measurements.

The correct answers are A) They use seismic waves. C) They collect data from seismographs. D) They measure arrival times of surface waves.

Geologists locate the center of an earthquake because they use seismic waves, they collect data from seismographs, and they measure arrival times of surface waves.

In the occurrence of an Earthquake, geologists use seismometers to locate the origin of the earthquake. The earth's movement produces an expanded wavefront that origins in the hypocenter of the earthquake. It's speed: seven kilometers per second. Electronically, the seismometer amplifies and records the information because the wavefront expands and is recording by each seismic station.
